JAMES ALLINGHAM, OF MITCHELL, DAKOTA TERRITORY.

COMBINED sTovE-PIPE SHELF AND DRAFT-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 363,572, dated May 24, 1887.

Application filed December 7, 1885. Serial No. 184,396. (No model.)

To aZZ whom. it may concern,.-

Beit known that I, JAMEs ALLI'NGHAM, a citizen of the United States, residing at Mitchell, in the county of Davison and Territory of Dakota, have invented certain new and useful Improvements in Combined Stove-Pipe Shelf and Draft-Regulator, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to a combined stove-pipe shelf and draft-regulator of that class which comprises an arrangement with the pipe leading from a stove to a chimney, a casing provided with or adapted to serve the function of a stove-pipe shelf, and an iuternally-arranged movable cone and pipe-section.

The construction of my present invention will be hereinafter described, and the novel features particularly pointed out in the claims.

Referring to the drawings, Figure I is a vertical transverse section ot' a stovepipe shelf and draft-regulator constructed in accordance with my invention. Fig. 2 is a similar view with parts in position to securea reduced draft. Fig. 3 is a side elevation illustrating a detail of construction. Fig. 4 is a detail, hereinafter described. i

Like letters indicate like paris in all the igures ofthe drawings.

A represents the upper end of a section of pipe connect-ed with the stove and communieating with a section, B, leading to the chimney. Between these sections is inserted my combined stoveA pi pe shelf and draft-regulator, which comprises an outer casing formed of two frusta of cones, C C', or any desired shaped shell, united at their bases and each terminating in a sleeve, B2, the lower one adapted to receive the section A, and the upper one to enter the section Bof the stovepipe.A Exteriorly there are secured to or arranged with the frusta of cones suitable devices for supporting culinary and other articles-as, for example, a hook, C3, for a lid-lifter or other similar implement, a rod, 0*, to serveas a towel-rack, and a shelf, C5, to support dishes and other vessels for the purpose of keeping them warm. An additional shelf, C, may., if desired, be secured to the section B of the stove-pipe proper. These features I do not consider essential, but as mere optional con; veniences.

The section C2 is provided with a curved inclined slot, Gl, the upper end, GS, of which is slightly curved to present a flat surface for maintaining the rod D arranged therein,against falling by gravity from the upper end of the slot.

The rod D extends completely across the section C and through a sleeve, E, arranged therein, so that when the rod is moved from one end to another in the slot the said sleeve E is elevated and depressed within the sleeve C?. The inner end of the rod D is secured to the inner wall of the sleeve by means of a plate, D', 'which has a perforation, D, and a slot, D, extending from the perforation to the end of the plate. Said plate is secured to the sleeve by rivets or otherwise. The length of the sleeve E bears such a relation to the slot G7 that when the rod is at the eXtreme upper or lower end of the slot a portion of the same is left uncovered, as shown in Fig. 2, for a purpose hereinafter mentioned.

Depending from the sleeve E is a series of suspensionstraps, F, the function of which is to support a cone, G. Depending from the cone G- is a series of suspension-straps, H, the function of which is to support a sleeve or pipesection, I. This pipe I is not essential so far as regards the devices employed for controlling the draft, and I may, therefore, omit the same-that is to say, the cone G, the frustum C, sleeve E, slotted section C2, and rod D are all that are required to perform the function of regulating the draft, and this is true whatever theangle or inclination of the cone or frustum is, so long as they are parallel.

The arrangement and proportions of the suspensionstraps are such that the cone and pipe-sections are supported concentrically with the sleeve C2 and pipes A and B, and the lower end of the pipe-section I is of such a diameter as to make a close connection with the pipe A when depressed, as shown in Fig. 1. The upper end of the section I projects slightly within the conc G.

This being the construction, the operation is as follows: In summer for controlling a iire in a stove the rod D is turned until it rests near IOO the lower end of the slot, so that the parts are in the relative position shown in Fig. l, when the products of combustion enter directlyinto the section I and impinge against the inner surface of thc cone G, and are conducted continuously around the lower edge of the cone and directed upwardly through the section E and sleeve (l2 to the pipe B, producing a draft approaching in its nature a direct draft. Vhen the rod D is swung into its highest position, so as to rest at the top (lg of the slot C7, as illustrated in Fig. 2, the cone G is brought into close proximity with the upper frustum of cone C of the casing, whereby, although the products of combustion have direct communication with the casing at the upper end of the pipe A, still their escape from the casi ng is in a measure prevented, there being but a slight space for their passage upwardly into the pipe B between the cone G and frustum C. This arrangement of the parts is intended for the purpose of checking the draft and retain` ing the heat within the casing, and when elevated sufficiently to forni an opening at the lower end of the sleeve E, as shown in Fig. 2, said vopening acts to not only further check the draft, but also as a ventilator, and permits of the entrance of the'external air into the sleeves E 'C2 and into the pipe B.

By using the regulator in the position shown in Fig. 2 the easing becomes heated and radi 'ates the same into the room for winter use, while by depressing the cone and sleeve, as shown in Fig. 1, said radiation by the casing is diminished, as would be desirable in suminer seasons. y By fastening the inner end of the rod D to the sleeve, as at D', only a single slot, C?, is re quired.

By presenting my cone G over the draft flue or pipe A, and with its point up, the products of combustion are caused to take a circuitous route up into and out of the cone, and the heat thereof is reflected downward and laterally against the lower portion of the case.

Having thus fully described my invention, what I claim is- 1. A combined stove-pipe shelf and draftregulator comprising a casing formed of two frusta of cones united at their bases, each provided with a sleeve at its smaller end, and the upper one provided with an inclined slot, a sleeve arranged therein and provided with an operating-rod extending through said slot and with suspension-straps, and an internal conc g and a pipesection connected to each other and supported by the suspension-straps to the sleeve, substantially as specified. p

2. The combination, with the frusta of cones C C', the former provided with a sleeve, C, having an inclined slot, C7, of an interior sleeve,`E, supporting an interior 'cone and pipesection, said sleeve being provided with an operating-rod,D, projected th rough the slot Cl, substantially as specified.

3. In'a draftregulator, the combination of a casing having a pipe-section provided with an inclined slot, a sleeve arranged in said sccti'on and having a rod passing through the slot, and a cone arranged within the casing and secured to the sleeve, vsubstantiall y as specified.

4. The combination of the sleeve E, the rod D, and the slitted and apertured plate D', substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES A LLINGHAM.
